Superposition of the aglycon binding sites. The active sites of LpPgb1 (green) with (a) β-glucosidase from P. polymyxa in complex with thiocellobiose (blue; PDB entry 2o9r
) and β-glucosidase from rice (b) in complex with laminaribiose (cyan; PDB entry 3aht
; Chuenchor et al., 2011) and (c) in complex with cellotetraose (cyan; PDB entry 3f5j
; Chuenchor et al., 2011) are shown. Hydrogen bonds involving laminaribiose are shown as broken lines.
